Simulation Package for a New Sensorless Control Strategy for PM Synchronous Machines and Brushless DC Machines

A novel control strategy, applicable to Permanent Magnet Synchronous Machines (PMSMs) and Brushless DC Machines (BLDCMs), was investigated and modelled by an academic team in collaboration with NEC Electronics Europe GmbH. The company has recently developed a new microcontroller, based on a simple sensorless control principle of PMSMs, which is equally applicable to Brushless DC Machines. The use of the new microcontroller in drive systems was modelled by the research team at the university using a Visual C++ environment and was compared with traditional control methods. Extensive simulations were carried out and the results validated the new control principle, which is simple to implement and cost effective if using the novel NEC Electronics Europe GmbH microcontroller. The performance obtained proves the novel control strategy to be at least as effective as the classical ones, at reduced cost. Typical applications are in the white goods industry.
